Aaron Lehmann 497edf6960 service: Avoid underflow in logs padding calculation ...

This command inserts a variable amount of padding in the log line:

    padding := strings.Repeat(" ", f.padding-getMaxLength(task.Slot))

If the service is scaled up, or the slot numbers are noncontiguous, the
subtraction can underflow, causing a crash.
